Flooding due to Delaware River ice jam closes part of Route 29

Flooding caused by an ice jam on the Delaware River has closed a portion of Route 29 in Trenton on Monday morning, officials said.

Route 29 south is closed at Calhoun Street in Trenton and detours are in place, according to 511nj.com, the state department of transportation's traffic website.

While Route 29 would normally be jammed on a Monday morning, most state offices are closed in observance of Martin Luther King Jr. Day.

As a result, delays are only 5 to 10 minutes as of 8:15 a.m.

Water levels are expected to peak at 20 feet, 6 inches at 7 p.m. Monday, the National Weather Service said. Flood stage is 20 feet.

An ice jam is stationary accumulation of fragmented ice that restricts water flow.

The Bucks County, Pennsylvania side of the river is also being affected in Yardley.

The ice chunks could remain in the river this week as temperatures aren't expected to climb higher than than the mid 30s.
